Consider the gene for the character “freckles”. We’ll use “F” to designate the dominant allele (which produces freckles), and “f” to designate the recessive allele (no freckles).

a. Suppose one parent has freckles. What are the possible genotypes for that parent? ____________________

b. Suppose one parent has no freckles. What do we know about that parent’s genotype? ___________________

c. If the parent with freckles is homozygous (FF), what proportion of offspring will have freckles?

A) None of them

B) 25%

C) 50%

D) All of them

d. If an offspring with no freckles is produced, what do we know about the genotypes of the parents, supposing that both have freckles? ___________________________________________________________________

Suppose I have 2 flowering trees, one that produces yellow flowers, while the other produces blue flowers. Moreover, I learn that each tree is true-breeding, i.e., it is homozygous for flower color. Then I perform a cross between the trees, i.e., interbreed them.

a. Suppose all of the offspring trees produce greenish (intermediate between blue and yellow) flowers. What kind of relationship between the alleles is indicated? _______________________________________

b. Suppose the offspring trees all have some yellow and some blue flowers. What relationship between the alleles is indicated? _____________________________________________

A gene can have only 1 specific phenotypic effect.TrueFalse
A gene having more than 1 phenotypic effect is called _______________________________.

Some characters (such as height and skin color) are known as quantitative characters. What does this mean? Give an example of a quantitative character.

5. A kidney-bean shaped eye is produced by a recessive gene, k, on the third chromosome of Drosophila. Orange eye color, called cardinal, is produced by the recessive gene cd on the same chromosome. A third recessive gene on chromosome three, e, produces ebony body color. Trihybrid females are testcrossed to produce 4000 progeny, as follows: 1761 kidney, cardinal 1773 ebony 128 cardinal 97 kidney 89 ebony, cardinal 6 kidney, ebony, cardinal 8 wild type 138 kidney, ebony

a. Which gene is in the middle?

b. What is the distance between genes k and cd?

c. What is the distance between genes e and k?

d. What is the distance between genes cd and e?

1a) If you have three genes H, M, and T located on three different chromosomes and you performed the following cross:

HhMmTt x hhmmtt

How many phenotypic combinations would you see?

1b) If you have three genes H, M, and T located on three different chromosomes and you performed the following cross:

HhMmTt x hhmmtt

where H is Hairy and h is hairless; M is Mindful and m is mindless; and T is Tall and t is short.

If there were 800 offspring, how many of them would be expected to be hairless, Mindful, and Tall?

1c) Assume that three genes are linked on the X chromosome: A, B, and C.

If the parental cross was AABBCC x aabbcc, you would expect all of the F1 to be AaBbCc

If you cross these F1 progeny with a tester (aabbcc), what is a possible outcome of the percentage of the offspring will have one of the parental types assuming the genes are linked?

(You can pick any valid percentage you would like; remember percent is 0 to 100)

Using Miller’s hypothesis for adaptive evolution of thrashers (Toxostoma) from a mockingbird (Mimus) ancestor as representing the standard evolutionary genetic model of the modern synthesis, explain how each of the following hypothesized processes of evolutionary diversification differ: (1) West-Eberhard’s “alternative adaptations,” (2) West-Eberhard’s phenotypic and genetic accommodation, and (3) McKay and Zink’s “Sisyphean evolution.” Include in part 2 a discussion of how genetic accommodation resembles and differs from Waddington’s hypothesis of genetic assimilation.
